Most of the massages are done in the spa hut. The only time we did not have ours in the spa hut was when we requested it in the hut down on SSB. I believe the only time they are extra is if you ask for one in your room.

To get a massage or spa treatment in the Spa Hut do you have to request it, pay extra or get a particular spa service?

Hey! We just returned from CSS 2 days ago and got an aromatherapy couples massage. There are 5 huts and my understanding is that all spa treatements are in these huts, all of them are wonderful, you can hear the ocean waves...Yes, you do pay extra for spa services, they have a "menu" upon check-in.
